WELL-DRILLING RIG.

Application filed September 18, 1926. Serial No. 136,884.

I This invention relates to improvements in Well drilling rigs, having for an object to provide rigs of this character with a novel and advantageous form of tail post adapted for use 7 in conjunction with that type of swing lever illustrated and described in my ropending application 'for atent Serial Number 112,110, to support t e usual sand reel of a-well drilling rig, permitting gt a multiplicity of vertical adjustments of the reel shaft bearing thereupon to correspond to similar adjustments of the bearing for the opposite end pf said shaft carried the swing lever.

It is also an object of the invention to provide a tail post utilizing a novelly-constructed base plate, having means thereon to permit of adjustment of the tail ost proper and its brace longitudinally oi the same and also, having means which willpermit of side or lateral adjustment, either toward or from the sand reel and its shaft. y i

It is also among the aims and objects of the invention toprovide a tail post of such construction as -will increase the efficiency of a rig equipped therewith and which, byreason of its rigid, rugged and durable con-- struction, will lessen the. incident operation costs in that the same will be'of materially greater lasting character and further, will allow of a complete salvaging and hence pera.

4 provided for the post proper, the same being mit'its usage upon a great number of well drilling operations with but minimum-re pairs and replacements.

Other objects of the invention will be in part obvious and in part pointed out hereinafter.

In order that the invention and its mode,

a of operation maybe readily understood by those skilled in'the art to which itappertams, I have in the accompanying drawing and in the detailed following description proved tail post showing the same in operabased thereupon, set-out one possible embodiment of the invention,

In these drawings:

' Figure 1 is a perspective of. the imt Figure 3 is a similar view taken at subupon Having more particular reference to the,

stantially right angles to the Figure 2 and illustrating the base plate connected to the adjacent sill timber of the rig bed,

Figure'4 is a horizontal-section taken onthe line 4-4 of the Figure 2 looking in.

the direction in which the arrows point,

Figure 5 is a similar section taken on the line 5-5 of Figure 2 looking in the direction in which the arrows point, and

Figure 6 is a vertical fragmentary sec-- tion taken on the line 6-6 of Figure 2 looking in the direction in which the arrows drawlngs, in connection with which like characters of reference will designate corresponding parts throughout, the improved tail post may be stated to comprise a supporting element or post proper including relatively opposed angle metal bars 1, the adjacent portions of which are adapted to be rigidly interconnected through the medium of rivets or othersuit'able fastening devices 2,-the intermediate portions of which carry metal fillers 3 arranged between the spaced and adjacent portions of said bars 1 whereby the samewill be rigidly-retained in rela tively spaced positions as is clearly indicated in -the- Figures 1 and 3.

A base plate consisting of complementally formed or shaped metal angle bars is indicated in its" entirety at this time by the numeral a. The angle bars making up this base plate 4 are rigidly interconnected in juxtaposed relation, after the manner as shown in the Figures 3 and 4 through the medium of rivets or similar fastening devices 5, the vertical portions of said bars of the base plate having a plurality of pairs of openings 6 and 7 formedtherein, the openipgs 6 being slightly. inclined 1n their relative disposition as respects the vertlcal axis of the plate whereas the openings 7 are in true perpendicular alignment, the purpose of which will be subsequently described. i

To permit of positive and firm securmg of the base plate 4 to an adjacent sill timberof an equipped rig bed, indicated for base plate 4 and are adapted to receive anchor bolts therethrough, the lower portions of such anchor bolts being extended a through openings in appropriate portions of said sill timber 8 and \engaged with suitable bearing plates'll countersunk in openings 12 in the lower side of said timber, as is shown in the Figure '3; the upper screw threaded" extremities of-said anchor bolts being passed through certain of the pairs of the openings 9 and then engaged by locking nuts or similar devices 13, thus firmly and rigidly connecting the said base plate 4 to "the upper surface of the sill timber .8.-

Because of the disposition of the pairs of openings 9 1n the horizontal portions of the X base plate 4, it will be understood that lateral or side adjustment of said base plate either toward or from the sand reel to be supported thereupon will be permitted.

The tail post proper 1 is adapted to be received upon and rigidly connected to the base plate 4 and to accomplish this, it will be understood that the lower portions of the angle bars making up such tail post proper are overlappingly engaged with the vertical portion of the base plate 4, that is, the lower the rigid interconnection of the angle barsv portion of the tail post proper 1 straddles said vertical portion of the base plate in the fashion fasshown in the 'Figures 1, 3 and 6; this being permitted by reason of of the tail post proper 1 through the medium of the rivets 2 and the metal fillers 3 carried upon the intermediate portions of the same.

Those portions of the tail post proper parallel to the vertical portion of the base plate 4 are formed with aligned openings adapted to receive superposed connecting bolts 14 therethrough, the intermediate portions of said bolts passing through the ad- ]acent'perpendicularly disposed openings 7, aforesaid, whereupon lockingnuts 15 are turned into engagement with their respective screw threaded extremities and, obviously, afford means for effecting-a practical and rigid connection of the tail post proper to the base plate 4. To further rigidify or stabilize the arrangement of the tail post proper 1 with respect to-the base plate .4, angle brackets designated by, the numeral; 16 are riveted or otherwise fixedly connected,

to the lower extremities of those. portions of the angle bars making up the tail post 1 and disposed at substantially right angles to the'vertical portio'nsvof. the-base plate 4,

.- the angular extremities of these plates 16 flus'hly resting upon adjacent portions of the horizontal partsof said baseplate 4 and thus afl'ording eifectual feet for said-lower extremity of the tail post proper 1.

That the tail post proper 1 may tually braced in itspositioning with respect to the base plate 4, whereby to increase riparallel portions of said angle bars. The

upper end of the brace bar 17 is provided with an extension shown in the Figure. 2 3

and designated by the numeral 18', such extension eing snugly received between adacent portions of the angle bars of the tail A post proper 1, whereupon it is fixedly secured or connected to the same throu h the medium of a rivet or other suitable astening device 19; the lower portion of the brace bar having straddling engagement with the adjacent vertical portion of the base plate 4 after the fashion shown in the Figures 1 and 2, whereupon connecting bolts 20 are passed through appropriately formed open-- ings in thesaine and through theadjacent pair of openings 6 in said vertical portion of the base plate 4, following which suitablelocking nuts or similar devices are turned into engage cut with their screw threaded extremities w ereby to render the connection between the base plate 4 and the lower portion of said brace 17 rigid and positive.

To further brace and rigidity the tail post with respect to the sill timber 8 receiving the same, I may and preferably dofixedly mount in the upper portion thereof a bracket plate 21, forming openings in the oppositev extremities of said plate and engaging the hooked ends of rods 22 in the same; these rods being arranged in diagonally opposed relation as is shown in the Figures 1 and 2 and in substantially parallelism to the sill' timber 8, while other rods 22' are loosely connected to strap brackets 23 connectedvto,

portions of the sill timber 8 as at 24 and have-their? free extremities screw threaded as at 25 whereby to. receive turnbuckles 26" thereupon, the opposite ends of said turnbuckles being engaged with screw threaded adjacent jportibns of the hooked rods 22, Thus, it will beunderstood that the usual turnbuckle braces are provided upon the op- I posite sides of the tail post construction and that by adjusting turnbuckles 26 thereof, the tension upon sald opposite sides of the tail post may be varied and consequently uponthis, the construction may be fabsolutely f braced and rigidified to the desired iii'cety; i Also, if desired, openings as indicated the numeral 27 may be formed in'portions Y of the upper ends of tail posts constructed in accordance with tlie invention andthese openings may be engaged by other suitable bracin devices or means, such as conditions or pre? rence may dictate.-

'With a view toward providing the tail post construction with means for receiving and permitting of vertical adjustment of a bearing box indicated in'its entirety by the numeral 28, I form in those opposed poralignment as is shown in the Figure?) and same to effect apositive connection of the with an oil pocket or opening 35 inorder.

delivered tothe ba In usage of my improved tail post, the

tions of the angle bars making up the tail post. proper 1 ar d arranged at substantially right angles to the verticalp'ortion of the base plate 4a pluralit of series of equispaced openings genera ly indicated by the numeral 29, the openings of: said several series being arranged in relative horizontal bearing box 28 to the tail post 1 and likewise, to prevent any lateral movement or vibration of said bearing box with respect to the adjacent ortion of the tail post.

It is preferab e, as I have described in.

my copendin-g application for Letters Patent, Serial Number 112,110 that the cap section 34 of the bearingbox 28 be provided that an effectual sup 1y of lubricant ma be itt linin s of said liox base plate 4 thereof 1s properly adjusted upon the upper face of-the sill timber 8 whereupon the anchor bolts 10 are passed through the adjacent o enings 9 inthe l'lOll- 'zon'tal portions of sai base plate and seouredin the sill timber in the manner hereinbefore stated. Obviously, by reason of j'the formation. of pairs of openings 9 in these horizontal portions of the base plate 4, saidplate may be adjusted sideways or laterally, that is, toward'or from the sand reel R supported by the tail post-1. Follow ing adjustment and securing of the base plate 4 upon the sill timber 8, the tail postroper and its brace' 17 may be then 'ad-' us'ted to the proper position upon the vertical portion of said base plate 4 by slid ing the lower portion of said tail post proper and said brace 17 longitudinallythere along until the proper positioning has been attained, whereupon the securing bolts 14 and 20 in the lower portions of these particular elements are passed through the adjacent I openings 6 and 7 and then fixedlysecured.

Thus, it willbe seen that lateral'andlongilever construction of t e rig.

tudinal adjustment of the tail post construction with respect to the sand reel'R, will have been secured.

The bearing box 28 may be readily adjusted vertically with respect to the tail post proper by removing the securing bolts 32 and the dowel pins 30 from, the openings 29 and re-engaging the same "with those openings-of the several series whereat the bearing box will be supported in the proper plane or position, following re-introduction of thedowel pins 30'into the proper o nings 29 with re-engagement of the loc ing bolts 32 in those openings-adjacent to the openings in the extensions 31' of the base section 31. By reason of the vertical adjustaliility of the bearing box 28 upon thetail post, it will be appreciated that the same may be positioned to accurately correspond to the vertical positioning of the bearingbox supporting the opposite end of a the sand reel shaft u onthe usual swing Manifestly, the construction shown is 'capable of considerable modlfication and such modification as is within the scope of my claims, I consider within'the spirit of my invention.
